Rei -Sailor Mars-.The leader of the Dark Kingdom, Queen Beryl, calls out Jadeite for his failures. She reveals to him and two other dark kings named Nephrite and Zoisite that the Legendary Silver Crystal is said to contain immense power. Meanwhile, Usagi meets a shrine maiden named Rei Hino. They soon realize that a girl has disappeared. They assume that it is connected to a rumor about a "Demon 6:00 P.M. Bus" that is said to spirit people away. While returning to the Hikawa Shrine, Usagi encounters the stranger once again. He reveals his name as Mamoru Chiba. As Rei laments living alone due to her mysterious powers, she sees a vision of Usagi being captured and rushes out. Jadeite captures Rei and takes her inside the Demon Bus. Usagi and Ami enter the portal, but soon realize it is a trap. When Rei attempts to stop Jadeite from using his ice powers to freeze Ami and Usagi, she awakens her own powers and transforms into Sailor Mars. After Usagi launches one final Moon Tiara Boomerang attack to trap Jadeite, Rei overpowers Jadeite's ice abilities with her own flames, forcing him to flee. As the missing children are safely returned to their families, a mysterious chest is flown into Japan.
